BIMI Setup: The Unified Standard for Visual Trust

BIMI (Brand Indicators for Message Identification) is an email security protocol that displays your verified brand logo directly in the recipient's inbox to boost open rates and brand visibility. It requires a strict DMARC enforcement policy (p=quarantine or p=reject) and a compliant SVG Tiny PS asset signature.

Core Prerequisites

• Strict Enforcement: Policy must be p=quarantine (100%) or p=reject. BIMI will not render on p=none.
• SVG Tiny PS Asset: Your logo must be an SVG file compliant with the Tiny Portable/Secure profile (managed by SentraDMARC).
• VMC Ownership: A Verified Mark Certificate is required for display in Gmail and Apple Mail environments.

Hosted BIMI: The CNAME Strategy

SentraDMARC provides a CNAME-First delegation engine for BIMI. By pointing your default._bimi selector to our infrastructure, we automate asset sanitization, hosting, and certificate rotation.

Information Gain: Instant Scaling

While DIY BIMI requires setting up a dedicated web server and managing VMC expiration cycles, SentraDMARC's **Hosted BIMI** provides sub-5ms global resolution and automated "Switch-Safe" logo updates without manual DNS intervention.
